This article breaks down that Week 4 upset from Jacksonville’s perspective, the coaching and defensive philosophy that made it possible, and what the result meant for the Jaguars’ early season identity under head coach Liam Coen. Every stat below comes from official box scores and season reports.

| San Francisco 49ers | Lost 26-21 | Outgained Jacksonville by 64 yards | First loss of the season |

Jacksonville’s Defensive and Special Teams Blueprint
Devin Lloyd: AFC Defensive Player of the Week
Linebacker Devin Lloyd was the driving force behind Jacksonville’s takeaway barrage, intercepting Brock Purdy twice, with the first pick coming off a tipped pass that set up a Jaguars touchdown drive. His two interceptions produced 10 points for Jacksonville’s offense and earned him AFC Defensive Player of the Week honors, a clear individual recognition for a performance that single handedly shifted the game’s momentum.
That kind of opportunistic, ball hawking defense reflected exactly the identity head coach Liam Coen had been building since taking over the Jaguars, an approach that had already produced at least three takeaways in every game through the first four weeks of the season. Entering this matchup, Jacksonville had already forced more turnovers in four games than it recorded across the entire previous season, a remarkable early season transformation for the franchise’s defensive unit.
Parker Washington’s Historic Punt Return
Wide receiver and return specialist Parker Washington delivered the signature individual play of the entire game, returning a punt 87 yards for a touchdown that extended Jacksonville’s lead to 26-14 in the third quarter. That score marked the Jaguars’ first punt return touchdown in eight seasons, dating back to Jaydon Mickens’ return in 2017, an achievement that added a historic dimension to an already statement making road win. Full details from that game are available through the Jaguars’ official game report.
Washington’s return came immediately after a San Francisco three and out, showing exactly the kind of field position battle Jacksonville had won throughout the afternoon. That single play accounted for nearly a third of Jacksonville’s total scoring output, a stark illustration of how much special teams execution mattered in this particular result.
Arik Armstead’s Emotional Return to Levi’s Stadium
Defensive tackle Arik Armstead, who spent nine seasons playing for San Francisco before joining Jacksonville, delivered the play that sealed the win, stripping Brock Purdy of the ball with less than three minutes remaining while the Jaguars led by five points. Linebacker Foyesade Oluokun recovered the fumble, ending any realistic chance of a 49ers comeback and setting off a heated confrontation between Coen and San Francisco defensive coordinator Robert Saleh, who accused Jacksonville of legally decoding the 49ers’ signals.
Armstead’s postgame comments reflected the personal significance of the moment, noting he had plenty of memories in that building and had just created another one. That kind of emotional, full circle performance against a former team added extra narrative weight to an already significant Jaguars victory built on defensive and special teams execution rather than explosive offensive production.
San Francisco’s Perspective in the Loss
Brock Purdy’s Turnover Riddled Return
Quarterback Brock Purdy, playing his first game back after missing two weeks with a toe injury, threw for 309 yards and two touchdowns but lost the ball three times, including two interceptions to Lloyd and the game sealing fumble to Armstead. That kind of high yardage but high turnover statistical line reflected a quarterback still working his way back to full rhythm after the injury layoff, with rust showing up specifically in ball security rather than pure arm talent or accuracy.
Purdy did show flashes of his usual sharpness, connecting with Jake Tonges on a 21 yard touchdown pass with 7:41 remaining that briefly cut Jacksonville’s lead to 26-21 and gave San Francisco a real chance at a comeback. That throw came immediately after Cam Little missed a 47 yard field goal attempt for Jacksonville, a sequence that made the game’s final minutes considerably more tense than the eventual final margin suggested.
Christian McCaffrey and a Resilient 49ers Effort
Running back Christian McCaffrey provided explosive plays throughout the afternoon for San Francisco, part of an offensive effort that outgained Jacksonville by 64 total yards and converted eight of 13 third down attempts, statistics that under normal circumstances would typically produce a winning result. That statistical dominance, ultimately overshadowed by the turnover battle, showed genuine fight from a 49ers team that refused to fold even after falling behind by two possessions in the third quarter.
San Francisco’s defense also contributed meaningful individual moments, with linebacker Fred Warner nearly intercepting Trevor Lawrence twice in the first half and the defensive front generating tackles for loss from Bryce Huff, Yetur Gross-Matos, and Deommodore Lenoir on Jacksonville’s opening possession. That kind of defensive pressure, while not fully reflected in the box score, showed San Francisco remained competitive on both sides of the ball despite the eventual result.

Jacksonville’s Broader 2025 Defensive Identity
This win over San Francisco fit into a much larger pattern Jacksonville established through the season’s first month, with the defense generating at least three takeaways in every one of the team’s first four games. That level of consistent ball production reflected specific schematic and personnel changes implemented under Coen’s coaching staff, prioritizing aggressive, opportunistic defensive play over a more conservative bend but don’t break approach.
That defensive transformation carried Jacksonville to a 3-1 start and its second such start in 18 seasons, a notable accomplishment for a franchise that had struggled with consistency in recent years. Coen’s postgame comment that the team kept finding ways to win, even when the offense stalled, reflected genuine confidence in a complementary football formula that had already proven successful multiple times through the season’s opening weeks.
Head to Head History
San Francisco had historically dominated this head to head series, winning by double digits in each of the previous five meetings between these two franchises before Jacksonville’s 2025 upset. That reversal made this particular result all the more significant, representing the first time Jacksonville had won a road game against San Francisco in three all-time attempts at that venue and continuing a series where the 49ers still lead 5 wins to 3 overall.
What to Watch Next
For the Jaguars, sustaining this level of takeaway production while continuing to develop Trevor Lawrence’s efficiency as a passer represents the clearest path toward building on this statement early season win. The complementary football formula, relying on defense and special teams while asking the offense simply to avoid mistakes, showed real promise but would need offensive growth to remain sustainable across a full season.
For the 49ers, addressing the turnover issues that undermined an otherwise statistically dominant offensive performance became the immediate priority following this loss. Purdy’s continued recovery from his toe injury, combined with better ball security in future games, would be essential for San Francisco to bounce back from its first defeat of the season.
The Emotional Subplot Between Coaches
Beyond the on field statistics, this game featured a notable postgame confrontation between Jacksonville head coach Liam Coen and San Francisco defensive coordinator Robert Saleh, who accused the Jaguars of legally decoding the 49ers’ offensive signals. That heated exchange, occurring after Armstead’s game sealing strip sack, added an extra layer of competitive intensity to what had already been a hard fought, physical contest between two teams still establishing their season long identities in the early weeks of September.
That kind of sideline confrontation, while ultimately a footnote compared to the on field result, reflected the genuine competitive stakes both coaching staffs felt in this early season matchup. Jacksonville’s willingness to defend its methods publicly showed confidence in the identity the team had built defensively, while San Francisco’s frustration reflected the sting of an unexpected first loss after a promising 3-0 start to the season.
Jacksonville’s Season Long Trajectory After This Win
This victory over San Francisco proved to be an important building block for Jacksonville’s broader 2025 season, part of a stretch where the Jaguars’ opportunistic defense consistently generated the kind of takeaways that could carry the team even during offensive struggles. That formula, relying on defense and special teams while asking the passing game simply to protect the football, gave Jacksonville a sustainable path to competitiveness throughout the difficult early weeks of divisional and conference play.
Coen’s approach, building a physical, disciplined roster capable of winning through complementary football rather than explosive offensive production, reflected lessons learned from successful franchises across the league that have found sustained success without necessarily having an elite statistical passing attack. This win over San Francisco offered an early proof of concept for that broader organizational philosophy heading into the remainder of the season.
Conclusion
Jacksonville Jaguars vs 49ers showcased exactly how defense and special teams can overcome a significant statistical disadvantage in total offense, with Devin Lloyd’s two interceptions, Parker Washington’s historic punt return touchdown, and Arik Armstead’s emotional strip-sack of his former team combining for a signature road win. San Francisco’s Brock Purdy and Christian McCaffrey showed real fight in the loss, but three costly turnovers proved too much to overcome against an opportunistic Jacksonville defense.
With Jacksonville building an early season identity around takeaways and complementary football, and San Francisco working to clean up the mistakes that cost the team its first loss of 2025, this result offered a clear window into both franchises’ developing identities heading into the rest of the season.
